By rough estimation I meant the fluid pouring out of the check bolt hole was hotter to touch than a human body (36-38deg) but not scalding hot (50+degrees).. I think itni estimation tu chaljati Hai.
Why can't temperature be estimated? I didn't get that point.. Isn't it what we do daily in our lives? I am sure if it was in a range like 80-90 degrees where touching would end up burning you one would have needed a separate instrument... In fact I had intended to use one of those flat forehead thermometers... But the fluid really started pouring out so I aborted the plan hehe
